Neither should a ship rely on one small anchor, nor should life
rest on a single hope.
- Epictetus

The diversity in the faculties of men, from which the rights of
property originate, is not less an insuperable obstacle to a
uniformity of interests. The protection of these faculties is
the first object of government. From the protection of different
and unequal faculties of acquiring property, the possession of
different degrees and kinds of property immediately results.
- James Madison, The Federalist (no. 10)
